The USS Challenger (NCC-74857) is an Intrepid-class Scout in service with Starfleet and the Federation during the late 24th century. The Challenger was launched from the Utopia Planitia Fleet Yards in 2384, and was commissioned in 2385, together with all the other starships that were built during that period for attachment to Vanguard Command. She was placed under the command of Captain Geordi La Forge. The Challenger was immediately assigned to serve as the scout ship of 68-starship strong Task Force Invincible commanded by Rear Admiral (upper grade) Jean-Luc Picard.
